JOURNAL-LUBRHCATOR..

Specification of Letters Patent.

Patented .April 17, 1906.

Application filed October l0, 1904. Serial No. 227,915.

To all whom t Uta/y concern:

Be it known that I, EDDIE W. HANCOCK, a citizen of the United States,residing at Savannah, in the county of Chatham and State of Georgia,have invented new and useful Improvements in Journal-Lubricators, ofwhich the following is a specification.

This invention has relation to ournal-lubricators; and it consists inthe novel construction and arrangement of its parts as hereinafter shownand described.

The object of the invention is to provide a means for conveying oil orother lubricant from a receptacle adjacent a journal-bearing to thebearing in such manner that the lubricant is economically used and atthe same time the bearing is amply supplied'with the lubricant.

The further object of the invention is to provide a simple, cheap, andeffective means for carrying into effect the aforesaid purpose. Themeans consists, primarily, of a well which is adapted to move verticallyand at all times in a horizontal position. Said well is located in theoil-receptacle, which may be fixed to or detachable from the bearing, asdesired. Said well is held in an elevated position by springs suitablyarranged or other equivalent means. The well is so constructed as tocontain a revolving disk, and the lower portion of the well is providedwith an opening through which the lubricant passes from the receptacleinto the interior of the well and comes in contact with the aforesaiddisk. A strainer, preferably separated from the well, is located overthe lower portion thereof and over the oil perforation above referredto. The lubricant in passing through said strainer is relieved of allsolid and foreign matter, thus freeing the lubricant within the well ofgrit and similar substances. The wheel within the well is adapted tobear against the shaft, axle, or journal within the bearing, and as thesaid shaft, axle, or jour-- nal revolves the oil is conveyed by the diskto the same, and the bearing is lubricated. The oil'that drips from thebearing may be conveyed back into the original oil-receptacle and may beagain used for lubricating purposes, as above indicated.

In the accompanying drawings, Figure 1 is a side elevation of theoil-conveying means detached from the oil-receptacle. Fig. 2 is a sideelevation of the oil-conveying means detached from the receptacle andshowing the strainerthereof removed. Fig. 3 is a longitudinal verticalsectional view of the oil-conveying means detached from theoil-receptacle. Fig. 4 is a transverse sectional view of theoil-conveying means detached from the oil-receptacle. Fig. 5 is a sideelevation of the lower portion of the oil-well, showing a means foropening or closing the oil perforation to regulate the supply of oiladmitted to the well. Fig. 6 is a longitudinal sectional view of aportion of a shaft and a sectional view of a journal-bearing having adetachable oil-receptacle applied thereto. Fig. 7 is a transversesectional view of the parts as shown in Fig. 6, and Fig. 8 is aperspective View of the oil-receptacle detached. A

As above indicated, the oil-receptacle may be iixed to or detachablefrom the bearing. The preferred form of such a receptacle, however, asused in connection with my invention is detachable.

-The receptacle 1 is provided with the concaved edges 2 2, which areadapted to 'lit under the bearing 3. The upper ends of the bale 4 arepivoted to the bearing 3, and the said bail is adapted to swing underthe receptacle l. The spring 4 its against the under side of thereceptacle l and is provided with a detent 5, which is adapted toreceive the lower portion of the bail 4. Thus the receptacle 1 issupported and its upper edges held in close contact with the bearing 3in the manner as shown in Figs. 6 and 7. The said bearing 3 is providedwith the shoulders 6 6, which enter the upper end of the receptacle 1.On two of its opposite sides the interior of the receptacle 1 isprovided with the lugs 7. Between the said lugs a frame 8 is adapted toht. The lower ends of the said frame 8 are made thin or pointed, as at 99, so that the said ends may be bent to make the said frame extend toany desired height within the oil-receptacle. Incisions are cut in thesides of the frame 8, and the spring-tongues 10 10 are formed, which areadapted to bear against the sides of the receptacle 1 for the purpose ofpreventing the said frame from having any lateral movement.- The pins 1111 extend from the top of the frame to the cross-piece 12 thereof andare surrounded by the coilsprings 13. The well 14 is located within theframe 8 and is provided with perforations that receive the pins 11 11.The said well 14 is adapted to move vertically, the said pins 1 1 1 1acting as guides and at all times maintaining the said well in ahorizontal position. The disk 15 is journaled in the well 14. The up-IOO per edge of said disk extends above the top of the well 14 andthrough a slot in the top of the frame 8 and is adapted to bear againstthe shaft or journal 16. The lower edge of said disk extends well downinto the bottom of the well 14. In one of its sides and near the loweredge thereof the well 14 is provided with an oil-inlet perforation 16.The plate 17 is located against the under side of the top portion of thewell 14. Said'plate 17 is provided with a screen 18, which completelyincases the lower portion of the well 14. Said screen 18 is held awayfrom the bottom of the well 14 by the lugs 19 or their equivalent. Theupper ends of the coilsprings bear against the plate 17 and are adaptedto maintain said plate and the well 14 in an elevated position, thetension of said springs, however, being just suflicient to maintain theperiphery of the disk 15 in contact with that of the shaft 16. Theobject of the said well is to permit only suflieient oil to pass to thedisk 15 for the purpose of lubricating the bearing of the shaft 16.Otherwise the disk would convey too much oil to the bearing, which wouldresult in flooding and waste.

For the purpose of regulating the oil admitted to the bottom of the well14, I provide a pivoted lid 20, (see Fig. 5,) which is adapted to beswung over the perforation 16 and partially close or completely closethe same. The side of the well 14 is provided with a series of punchdepressions 21, which are adapted to receive the slightly-bent-downcorner 22 of the cover 20, and thus hold the said cover in a desiredposition with relation to the openin 16. The said cover is also providedwith a ug 23, by means of which the said cover may be moved.

The oil or lubricant is placed in the receptacle 1. rIhe 'oil passesthrough the strainer 18. Then it passies through the opening 16into thebottom of the well 14, when it is taken up by the disk 15 and conveyedto the shaft or journal 16', whichin turn carries the same into thebearing. It is obvious that any eX- cess of oil from the bearing willflow back into the receptacle 1, when it is again taken up and used asabove described.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, isF

1. A lubricator comprisin an oil-receptacle, a well located within saireceptacle and having an oil-opening7 a disk journaled in said well, andmeans adapted to move said well and disk vertically only while held in ahorizontal position.

2. A journal-lubricator comprising a detachable oil-receptacle adaptedto engage at its upper edge a journal-bearing, a suitable oil-conveyingmeans located within said receptacle, a bail pivoted at its ends to thebearing and adapted to receive said receptacle and hold the same inposition.

3. A journal-bearing comprising a detach-` able receptacle, anoil-conveying means located within said receptacle, a bail pivoted atits ends to a journalbearing and adapted to receive said receptacle, anda spring located at the bottom of said receptacle for retaining saidbail.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.

EDDIE W. HANCOCK.
